Hopes and Fears — Peter Turnbull

The body of a young Russian girl is found in woods near York in midsummer but she is not just dead, she's frozen ...
DCI George Hennessey knows that there is good and bad in everyone, and everything. So when he sees the condition of the young girl's corpse he knows that even though it signifies a terrible death, it also means that the killer must be local, as any time in transit would have affected the body's temperature. It is just lucky that she was discovered so soon and that this vital clue remained to give a good chance of bringing the criminal to justice.
All Hennessey has to do now is find out why a naive young exchange student became the target of a callous murderer. Was she killed by a jealous lover? Did she discover a dangerous secret? Or was she simply the victim of a vicious psychopath? The girl's background suggests nothing sinister at first, in fact no one seems to know her. But Hennessey is sure they are lying. Somehow she is connected to some of York's less attractive elements and one of them has killed her. Armed only with two obscure leads - a strange beggar girl and a single name - York's finest detective, aided by forensic pathologist Louise D'Acre and fellow CID officer Yellich, is determined to catch the killer.
